After the Rivals100 and the Rivals250 rankings were updated last week, the next piece of the rankings puzzle was put into place today when Rivals.com unveiled the latest rankings changes for the offensive positions. On the offensive side of the ball, nine new players saw their rankings jump up to the four-star level, including Miami Northwestern quarterback Jacory Harris.

Harris, who is 6-foot-4 and 169 pounds, is now ranked as the nation's No. 3 dual-threat quarterback. The Miami pledge has been playing lights out on the field this season, and his rise up the rankings also was sparked by a strong showing at this summer's Elite 11 Quarterback Camp.

"The kid is a tremendous competitor, and I'm really looking forward to seeing him play against Miami Central in the Orange Bowl," Rivals.com recruiting analyst Barry Every said. "To go through a major coaching change like he did and still do everything he has done on the field this season is amazing. I know some might knock him because of his weight, but he reminds me a lot of Colt Brennan out at Hawaii. Colt's not the thickest kid around, but he's a winner  just like Jacory is."

Harris wasn't the only quarterback that saw his ranking shoot up.

Joining him at the dual-threat position on the climb was Copperas Cove, Texas, playmaker Robert Griffin. The 6-foot-3, 195-pounder was one of Central Texas' most heavily recruited offensive players, but he decided to commit to the Houston Cougars. He's an excellent fit for what Houston does with its quarterbacks and is expected to help bolster the Cougars' offensive attack early in his career.

At all-purpose back, two players also moved up to the four-star level.

Onterrio McCalebb of Fort Meade, Fla., and Jeff Demps of Groveland (Fla.) South Lake moved up to four stars and are ranked No. 9 and No. 10 at the position respectively. McCalebb, who is 5-10 and 154 pounds, is already committed to West Virginia and should be deadly in the Mountaineers spread-option attack. Demps (5-8, 162) is leaning toward Florida and Tennessee, but also has scholarship offers from Virginia Tech, Auburn, Arkansas, Kentucky, Ole Miss and others.

Three new receivers also received four-star nods.

Jarrett Sparks of Merced, Calif., moved up to four stars and is now ranked as the nation's No. 46 receiver. Sparks has been destroying defenses on the field this season and he's got some of the top teams on the West Coast chasing after him. Arizona, Arizona State, Cal, Oregon State and Washington State are in the mix with Sparks.

Purdue commitment Roy Roundtree of Trotwood (Ohio) Madison also moved up from the No. 57 spot to No. 44. He also saw a rise in his ranking to four stars. Roundtree was always one of the top receivers in Ohio, but this season on the field he's proven he's one of the top receivers in the nation. Playing on a team full of blue-chip talent, Roundtree has come to play every game and is a threat to score every time he touches the ball.

Brandon Ford of Hanahan, S.C., also moved up and is the No. 45 receiver and a four star. The 6-foot-4, 205-pound Clemson commitment pledged to the Tigers before the process really could even get started. As a junior, Ford had 63 receptions for 651 yards and seven touchdowns.

Tallahassee (Fla.) Lincoln tight end Jabaris Little is now also a four star. The 6-foot-4, 240-pound Florida State commitment impressed Every when he saw him play in person earlier this fall.

"He looks great in pads and was better than I thought going in," Every said. "He's listed as a tight end in the database, but played linebacker. He runs well for a big kid and hustles."

Virginia Tech saw one of its prize recruits  offensive tackle Bobby Massie  move to a four-star prospect and the No. 34 player at his position. Massie is a mountain of a man at 6-8 and 335 pounds, and he's gone out this season and showed he potentially could be one of the best Hokie linemen in recent history.

Lakeland (Fla.) Lake Gibson offensive center prospect Ricky Barnum might be a little light now  he plays in the 6-2, 250-pound range  but he's not light on talent. He's one of Florida's best run blockers and his senior season has propelled him to four-star status. Barnum has offers from Alabama, Florida, Georgia, Georgia Tech, South Carolina, South Florida, West Virginia and others, but for some reason fails to get mentioned a lot when talking about the best line prospects in the nation. Maybe that'll change now.

Other notable moves at running back included jumps up in Rivals Ratings for two Illinois stars  Mikel LeShoure and Jason Ford. Both are now ranked as 5.7s on the Rivals Rating Scale based upon the play of their senior seasons. Few have been better in central Illinois than LeShoure and Ford, a soft Iowa commitment, has been tearing it up in the St. Louis area.

Missouri pledge Drew Temple of Kansas City (Mo.) Rockhurst also saw his stock shoot up to the three-star level. He now ranks as the No. 41 running back in the nation. Overall the Tigers saw three of their offensive players move up a star level. Along with Temple, Gahn McGaffie and Daniel Jenkins are also three stars now.

Auburn running back commitment Reggie Hunt moved down from the four-star level to the No. 21 all-purpose back. But the Tigers did see positive movement with receivers Damion Allen and Harry Adams. Adams, a 6-foot, 175-pounder from Fort Lauderdale, Fla., moved up 17 spots and increased his Rivals Rating to 5.7. Allen moved up 16 spots and also increased his Rivals Rating to 5.6.

Several receivers took tumbles down the rankings.

Cordale Scott of Cleveland Glenville went from 16 to 28. Las Vegas Canyon Springs receiver Raevon Samuel has had an up and season and he's now at No. 68 and is a three-star prospect. Kendall Wright from Pittsburg, Texas, slid to No. 69 after previously being at No. 44.
